And know that Allah is with the righteous. 123 And whenever a surah is revealed there are some of them who say: Which one of you hath thus increased in faith? As for those who believe, it hath increased them in faith and they rejoice (therefor). 124 but as for those with sickness in their hearts, it adds defilement to their defilement and they die in a state of denial of truth. 125 Do they not observe that they are tested once or twice every year? Yet they do not repent, nor do they heed advice! 126 And whenever a sura is sent down, they look one at another: 'Does anyone see you?' Then they turn away. God has turned away their hearts, for that they are a people who do not understand. 127 A Messenger from your own people has come to you. Your destruction and suffering is extremely grievous to him. He really cares about you and is very compassionate and merciful to the believers. 128 But if they turn away, say (O Muhammad SAW): "Allah is sufficient for me. La ilaha illa Huwa (none has the right to be worshipped but He), in Him I put my trust and He is the Lord of the Mighty Throne. 129
